UNCOUPLING DEVICE.

Application filed June 1, 1920. Serial No. 385,780.

To all whom it may concern:

Be it known that we, IsAK MonLLER and REUBEN ARiuvnIeH'r, subjects of the King of Great Britain, and residents of the city of New Glasgow, in the Province of Nova Scotia, Dominion of Canada, have invented certain new and useful Improvements in Uncoupling Devices, of which the following is a specification.

This invention relates to improvements in uncoupling devices, and the objects of the invention are to provide a simple and effective form of connection between the crank arm of the operating rod and the coupling pin and further to provide such a form of supporting bracket for the operating rod as will enable it to be readily attached and detached.

Further objects of the invention are generally to improve and simplify the construction of the various parts to better adapt them to perform the functions required of them.

It consists essentially of the improved construction, particularly described, and set forth in the following specification and accompanying drawings forming part of the same. y

In the drawings;

Figure 1 is a view of an end of the freight car having our invention applied thereto.

Figure 2 is a side view of the same.

Figure 3 is a detail front elevation of the supporting bracket.

Figure 4 is a detail side elevation of the supporting bracket.

Figure 5 is a detail in plan of the arm on tne operating rod,

Figure 6 is a detail sectional elevation of the connecting link between the crank arm and the coupling pin.

4 In the drawings, like characters of refer ence indicate corresponding parts in all the figures.

Referring to the drawings, A represents a freight car of any suitable standard design. B indicates an operating rod for the uncoupling device having one offset end 10 adapted to constitute a hand operating lever, and another ofi'set end 11 formin the crank arm by which the pin is lifted. he arm 11 is formed at the end with an eye 12 adapted to fit around the connecting link 13, which is formed with turned ends 14 and 15, which extend laterally and prevent the eye sliding oii' the link.

By reference to Figures 5 and 6, it will be seen that the link 13 is formed from a single metallic rod bent to form an elongated eye 16 at the lower extremity which fits through a perforation 17 in the coupling pin 18, the offset ends of the rod being brought together to form a central shank 19, and then being bent outwardly to form a T-shaped end constituting the hook shaped extremities 14 and 15.

The operating rod B is held in position by a bracket 20, on the side, and by a bracket 21 at the centre. The bracket 21 at the centre of special design, being formed with a side plate 22, a bottom plate 23 and an inclined mouth or socket 24adapted to receive the rod B, and in which it is adapted to be retained by a suitable cotter pin 25.

Owing to the angular disposition of the mouth 24 it is possible to readily-remove and insert the operating rod. In inserting the link, it is first drawn up vertically, and the end is then connected to the link and then slid backwardly into the socket 24 in the bracket, and located therein with a cotter pin, afterwards the side bracket 20 is attached. to suitable holes.

As many changes could be made in the above construction, and many apparently widely different embodiments of our invention, within the scope of the claims, constructed without departing from the spirit or scope thereof, it is intended that all mat ter contained in the accompanying specification and drawings, shall be interpreted as illustrative and not in a limiting sense:

What we claim as our invention is:

1: In car coupling device, a connecting link formed from a single piece of metal bent upon itself to form an eye at one end and having a shank formed by two parallel abutting portions of the metal the ends. of

which. are bent laterally in the plane of the eye at the outer end, as and for the purpose specified.

2. In an uncoupling device, the combination with a coupler locking pin having an eye at its upper end, and an uncoupling lever having its inner extremity formed into a vertically extending eye, of a rigid link have 111;: suli stantially parallel arms, said link In Witness whereof we have hereunto set having an elongated loop formed at one exour hands in the presence of two Witnesses. 10 trennty engaging the coupler locking pin ISAK MOEIQLER. eye, said parallel arms passln throu 'h said uncoupling lever eye and hai ing th eir ex- REUBEN ARKWRIGHT' tremities turned outwardly in the plane of Witnesses: the link body to limit movement of the link OLIVJ J D.
